Oh, come on! Why do you think these aeroplanes are so painted? FINANCE! It costs a fortune to support them, and if painting them in Red Bull colours means they fly rather than moulder in a museum, bring on the glitzy paint!
In fact that Vulcan thing (Vulcan to the Skip?) could do with following that course of action - get some real sponsorship behind it instead of rattling the begging bowl several times a year. But I understrand it was a condition of ite lottery grant that it stays in RAF colours. Pity.
